Study Notes

Electric Circuits and Current

Electric current is expressed in amperes (A), with 1 ampere equal to 1 coulomb per second.

The Role of Switches

A switch in an electric circuit functions to control the flow of electric current by opening or closing the circuit.

Effects of a Broken Circuit

When a circuit is broken, the electric current stops flowing.

Flow of Charges in a Torch

The flow of charges in a torch is provided by a battery, which enables the bulb to glow.

Components of an Electric Circuit

An electric circuit consists of a conductor, such as a wire, a source of voltage (e.g., a battery), and a device that uses the electric energy (e.g., a light bulb).
